Strikes
threaten to disrupt airports in the UK
The UK Border Agency has warned passengers to expect delays at Heathrow and
other UK airports on Thursday. Hundreds of immigration
and customs officials are joining other union workers in a national labour
strike over changes to pensions, reports The Guardian.

Hotel terror in Kabul
In the Afghanistan capital, eight suicide bombers attacked the Hotel
Inter-Continental (not part of the InterContinental chain) in a
brazen, carefully orchestrated plot, reports BBC News. NATO forces ended the
siege, which killed 10 people. Our condolences go out to the grieving families.

An augmented-reality tour of the Berlin
Wall debuts
You can now see
photographs of the Berlin Wall where it used to exist by downloading a
mobile application that uses augmented reality technology, Der Spiegel reported in its latest issue. The app works by
combining GPS (to pin down your location) with your device's internal
compass and camera viewfinder, to recreate the concrete barrier built by the
German Democratic Republic to encircle the city of West Berlin. Users of
iPhones and Android devices can download the app.

Free entry
days at the Taj Mahal upset conservationists On 28 to 30 June, the Taj Mahal will be
open for free to commemorate the life of its creator, Mughal emperor Shah
Jahan. But conservationists worry that the
additional visitor traffic will likely damage the 17th-century monument,
reports The Times of India, as the monument's pavements and staircases are
being worn away.
